Wireless AP authentication failure.

Userlevel 1
I am seeing this message on both my Identifi Controller V2110, as well as in the Netsight Console. "A Wireless AP has attempted to connect with outdated key information. Wireless AP authentication failure. " This only seems to be occurring on the secondary channel to the backup controller!!! What happens is the secondary channel cannot be established. Netsight Suite is currently running and Identifi is on The model AP is 3825i. Please advise how I may resolve this issue. Thanks

This typically means that the key pairs that have been exchanged between controllers in your High Availability Pair have become invalid for some reason.

To fix this, we briefly make both controllers "Standalone" (making note of which IPs were used to build HA on each side, which controller is configured as "Primary", and which (if any or both) synchronization options have been configured FIRST) and what the Fast Failover timeout value has been set for ... for a minute or two ... thereby breaking the pairing ... and then after that brief stint as two separate and standalone controllers ... re-pair them using the settings you had in place previously.

This should fix things for you.
